DIE-PRESSNG- APPARATUS.

Application filed September 29, 1923. Serial No. 665,697.

To all 'whom t may concer/n.'

Be it known that l, Josnrni 7. GonooN, a citizen of the United States, anda resident of Baldwin, county of Nassau, and State of New Yorl, have invented a certain new and useful Die-Pressingl Apparatus, of which the following is a specification.

The invention relates to apparatus for forming` characters on the wheels or discs of numbering machines, cash registers, calculating machines, and the like.

The objects of the invention are tok provide an apparatus which will be cheap to construct, of economical operation; of siniple, strong` and rugged construction; which will not easily get out of order; which is easy to repair, and by nieansof which a plurality of characters or groups of characters may be formed simultaneously.

One embodiment of the invention is illus trated in the accompanying drawings, in which like parts `in all of the several figures are designated by corresponding characters of reference, and in which Fig. 1 is a top plan view of the preferred embodiment of the invention, a portion of the mechanism being removed.

Fig. 2is`a detail side elevation of a form of stop.

Fig. 3 is a plan view of a form of holder.

Fig. 4 is a section on the line 4 4 of Fig'. 1, a portion of the apparatus being in sido elevation.

Figs. 5, 6 and 7 are diagrams showing various positions assumedl by a matrix bar in carrying out the process of the apparatus, and Y Fig. 8 is a detail' section taken on the line 6, 6 of Fig. 1. y

In carrying out the invention a base comprising parallel sides 1, 1 is employed. The base is preferably mounted on a bench or pedestal, and carried by the base is a circular bed plate 2. p

The upper surface of the bed plate is pro vided with `a central cylindrical chamber 8 and with an annular shoulder 4 on its outer periphery, said shoulder and recess defining the boundaries of an annular table 5, and the table is formed with an annular shoulder 6 around its outer periphery.

The table is provided with a circular series of radially arranged rectangular recesses 7 each open at the top and at each radial end. That portion of the table in which therecesses 7 are located is narrow compared with the distance between theperiphery of the chamber 3 and the shoulder 4, on which latter is carried an annular wall 8, and an annular recess 9 is thus formed betweenthe wall and the partitions between the recesses 7 lVithin each recess 7 is slidably disposed a parallelopipedon formed block 10 having a threaded bore 11 in which is mounted an externally and internally threadednut 13. The female threads 14 of the nut are of a pitch different from the malle thread 15 thereon.

Mounted in the annular wall 8 is plurality of stub shafts 16 each shaft being in radial alinement withA the bore of one of the nuts 13.` Mounted on each shaft 16 and in the annular recess 9 is a bevel pinion 17. Each stub shaft has a threaded extension engaging the female thread of alnut. Each nut is provided with an unsymmetrical head 18 whereby the nut maybe rotated to adjust the positions of the blocks 10 axially toward and away from the center of the bed plate 2.

Lying within the reces 9 and in mesh with all kof the piuions 17 is a circular, bevel rack 19. An annular plate rests upon the rack 19 and the partitions betweenthe recesses?, and covers the said recesses, and retains the blocks 1() in position. A ring 21 bolted to the wall 6 retains the rack 19 and plate 20 in position. I

A stub shaft 22 is -journaled in the wall 8 and one of a triangular partition and carries a bevel pinion 23 which meshes with the rack 19. One end of the shaft 22 project-s beyond the outside periphery of the wall and carries arms 24 or the like whereby the rack may be revolved around the 'center' of the baseplate, and motion be transmitted to all of the pinions 17 whereby all of the blocks may be simultaneously and equally moved radially toward or away from the center line of the base plate as the shaft 22 is rotated in one direction or the other.

Each block 10 is provided at its inner end with a pairof spaced, perforated lugs 2 5, and between each pair of lugs is pivoted a matrix lever 26.` AThe levers are in radial arrangement, and when a number of them are employed or when they eXtendfwell toward the center, the sides may be beveled, as shown in Fig. 1.` k

In the embodiment of the'invention illustrated each lever has-its free end formed to an arc struck from the pivotal point of the lever. The top and bottom sides of the free extremity of the lever' are rounded to circular form, the circle beingstruck from the point at the center of the arc-shaped face 27 of the lever, and the top and bottom arcs overhang the face 27 as illustrated.

Into the face 27 of the lever is cut, in intaglio, the character, group of characters or other design which it Ais designed to have formed on the disc, wheel or other object.

The base plate is provided with a central perforation 2S which forms a bearing for a plunger 29. The lower yprojecting end of the plunger carries a grooved `fitting 30 which is engaged by the forked end of a. lever 31 ofthe first class pivoted inthe side members 1, 1. The opposite end ofthe lever is Ueshaped and engages an eccentric 32 mounted on Va shaft 33 to which power may be.y applied in any desired manner.

The plunger 29 extends through the bed plate 2 and near its upper end is provided with-a flange 34, and carried 'on the flange by means of a plurality of coil springs 35 isa movable collar 36.

The vupper end -of the plunger is bored and tapped for the reception of a tap bolt 37 having` two shoulders 3S and 39 and a i polygonal head. On the bolt 37 is threaded the disc 40 lto be operated upon. .Va'shers 41 and 42 are lplaced one on either side of ythe disc 49, vand between the washer 42 and the shoulder 38 is a washer 43, the latter, and the shoulder 39 forming 'a 'peripheral groove 44 around the bolt 29 for a purpose to be hereinafter described.

The operation is as followszf As shown in Figs. 1 and 2 the apparatus is in the position after the process has been carried out. The shaft 22 is rotated lin the anti-clockwise direction, the rack 19 is revolved causing the blocks 10 and levers 25 to be simultaneously moved away from the center, thus releasing the disc 42.

The stud bolt 29 and with it the washers 41, 42 and 4S, and the disc 40 are removed from the plunger 29. Because of lthe pressure which has been applied to the surface of the disc, the latter will be frozen to the stud bolt; The pivoted leaves 45, and 46 of the holder 47 are swung apart and then closed around the stud shaft, the opening` 48 engaging the recess 44 between the shoulder 39 and washer 43. The stud bolt may 'now be driven out of the disc 40 and the washer.

The washers are now reassembled on the stud `bolt with a new disc between the washers 41 and 42, and the stud bolt is positioned on the plunger as before. The shaft 22 is now rotated in the clockwise direction to move the levers 26 inward to contact with the new disc 40. `When the faces 27 of the levers 26 Iengage the surface of the discs, a

knob 49 is slipped down over the end of the bolt 37 and rests upon the free ends of all of the levers 26.

Power is applied to the shaft 33 and the plunger 29 is given a reciprocating motion axially in its bea-ring. The operator will apply-pressure downward on the knob 49 whereby the levers 2G rock in unison with the oscillations of the plunger.

During this operation the operator continues to feed the blocks 10 and levers 26 toward the center by turning the shaft 22 in the clockwise direction. The rolling kneading or knuckling movements of the faces 27 of the matrix levers will cause the metal of the disc 40 to flow, as it were, into the intaglio characters cut in the faces whereby the characters in relief, will be formed on the edge of the disc.

The movement of the levers inward is limited by the engagement of a finger 50 0n the shaft 22 with a stop 51 carried yby the ring v21.

Then the metal of the disc beginsto enter the matrices, the hand of the operator may be removed from the knob 49, or the knob may be removed, and the bite vof ythe levers against the disc will cause the levers to pivot.

To adjust the apparatus to operate on discs of various sizes,'a wrench may be applied to the heads 18 of the nuts 15'and the blocks 10 may be set to any diameter desired. The ringl 1 is provided with opening 52 for this purpose.

It will be understood that when it .is desired to cut or press characters in the dis'c, the matrix characters must be in relief.

Preferably the levers should be arranged in oppositely disposed radially `alined pairs whereby the thrusts will be vevenly distributed, and there will be no strains placed upon the plunger 29.

Then it is desired to produce a Adisc 4having an uneven number of characters such, for example, as the day rof the month disc of a time stamp, the levers should be even in number, and the face 27 of one of them should be blank.

The invention is not, however, limited to the use of an even number of 'matrix levers, as a'n uneven number may be employed if desired.

In the drawings the plunger 29 is illustrated as operating vertically but it is to be understood that this is not essential to the operation. The reciproeations of the plunger may be in any direction so long as the feeding movements of the levers are at right angles to the axis of the plunger.

In accordance with the provisions of the patent statutes lthe 'principle of vthe in'vention has been described', together with the apparatus which is now considered to represent the best embodiment thereof, but it is desired to have it understood that the ap.- paratus shown is merely illustrative, and that the invention may be carriedv out in other' ways.
